Title: State machine for trail management system
Inventor: DAVIS NIGEL ROBERT
IPC: H04L12/70
Filed: 1998-11-27
Abstract: A trail management system for a transport network comprises a database storing data describing each of a plurality of actual and intended/planned trails within a network. Each trail is described in terms of a state model, in which the trail is recorded as being in one of a plurality of stable states, eg ready for service, not ready for service, existing in the network but not fully recorded in the network management system, or assigned for deletion from the network. The trail data is modified by a set of automatic processes, by means of which a trail data may transition between stable states. Each trail data may adopt one of a plurality of sub-states, eg fully provisioned, incomplete, in conflict with another trail, inconsistent with another trail, unprovisioned, or unsupported by network resources. The network management system learns of actual existing trails within the network and checks for consistency of actual trails with stored trail data.

Title: Method and apparatus for dual chamber cardiac analysis
Inventor: ARMSTRONG RANDOLPH K
IPC: A61N1/372
Filed: 1997-09-15
Abstract: A method and apparatus for analyzing cardiac information involves recording both atrial and ventricular information related to a recognized event. This information can then be transmitted by telemetry to the physician and graphed on a common graph which plots both atrial and ventricular information over the time period of the event. This technique allows greater ability to discern the true nature of these events, including whether a given event is a sinus tachycardia due to exercise or a ventricular tachycardia which might necessitate treatment. Therefore, the present invention enables more accurate analysis of cardiac information and thereby makes possible the more appropriate application of treatment.

Inventor: THOMAS JOHN H
IPC: A01M9/00
Filed: 1999-04-23
Abstract: Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable. A clutch permits the user to discontinue dispensing material from the device at the selection of the user, and automatically discontinues dispensing of material when the apparatus is driven in a reverse direction.

Title: Oxygen delignification process of pulp
Inventor: KANG GUO JUN
IPC: D21C9/10
Filed: 1998-01-19
Abstract: The present invention is concerned with a single stage method delignification process for pulps, preferably sulphite pulps. The improvement to conventional oxygen delignification process comprises in situ addition of a reducing agent substantially non-reactive with oxygen. The end result is a pulp having enhanced strength properties and higher viscosity. Sodium borohydride is the preferred reducing agent, and MgO is the preferred alkali source. Similar results can be obtained with a two-stage oxygen delignification wherein the pulp is treated with the reducing agent in the first stage, and then washed and pressed conventionally before proceeding with the oxygen delignification in a second stage.
